There's an active memory-improvement community at <a href="http://artofmemory.com" rel="nofollow">http://artofmemory.com</a> including forums and a wiki of techniques.<p>Why bother? Because these techniques increase the capacity of "cache" that is closer (low latency) to human "computation". This can lead to faster traversal of the OODA loop, <a href="https://en.m.wikipedia.org/wiki/OODA_loop" rel="nofollow">https://en.m.wikipedia.org/wiki/OODA_loop</a>, which is relevant to lean startups, business competition, combat and more.<p>See the HN thread on AI as an enabler of IA, <a href="https://news.ycombinator.com/item?id=10373180" rel="nofollow">https://news.ycombinator.com/item?id=10373180</a><p>In addition, spaced-repetition techniques can be used to increase your vocabulary, which is like gaining extra pixels for the expression of nuanced goals, helping any compass which guides execution to a goal. Words are proxies for dreams and dangers, especially in a software-constructed world. Greater word capacity becomes greater visibility over a software-based terrain.
